T0 0/ whom, it may concern.-

Beit known that I, JOHN M. W. LONG, a citizen of the United States, residing at Hamilton, Butler county, Ohio, (post-office address Hamilton, Ohio,) have invented certain new and useful Improvements in Disk Plows, of which the following is a specification.

This invention pertaining to improvements in disk plows will be readily understood from the following description, taken in connection with the accompanying drawings, in which Figure 1 is a plan of a single-disk plow embodying my improvement; and Fig. 2, a perspective view, on an enlarged scale, of the beam-head casting.

In the drawings, 1 indicates the plow-beam 2, the plow-disk journaled thereto at an angle; 3, the front furrow-wheel; 4, the landwheel; 5, the rear f urrow-wheel, all the parts thus far referred to being as usual; 6, the beam-head casting, rigidly secured to the forward end of the beam and presenting a fiat upper surface projecting furrowward therefrom; 7, the tongue, a short affair extending rearward from the hitch-point of the draftgear to a pivotal connection with the beamhead casting; 8, the main pivot-point for union between the beam-head casting and the rear end of the tongue, this point being located substantially in the line of strain extending through the disk and parallel with the line of travel of the implement; 9, a secondary pivot-hole in the beam-head casting to the landward of pivot-point 8; 10, a stoplug on the beam-head casting in position to be engaged by the tongue and limit its swinging in the furrowward direction; 11, a stop formed by the forward portion of the beamhead casting and adapted to be engaged by a landward projection of the axle of furrowwheel 3 when the tongue is in normal straight position, the axle of furrow-wheel 3 being strongly stirruped to the tongue, so that wheel 3 swings with the tongue; 12, an evener piv-,

oted to the forward end of the tongue and adapted for use with either three horses or two horses, the drawings showing it provided for three horses; 13, a pivot-point in the evener where it is pivoted to the front end of the tongue when three horses are used, this pivot-point being located one-third the length of the evener from its furrowward end; 14, a pivot-hole in the evener located at the midpoint in its length and adapted for use in pivoting the evener to the forward end of the tongue when two horses are used; 15, the doubletree shackled to the furrowward end of the evener 16, the sin gletree shackled to the f urrowward end of the doubletree; 17, the singletree shackled to the landward end of the doubletree; 18, the singletree shackled to the landward end of the evener, and 19, 20, and 21 lines and points upon the drawings for use in demonstration.

In the use of disk plows it is of the utmost importance that the f urrowward horse walk in the furrow. Sometimes two horses are used and sometimes three horses, and it has heretofore been found impracticable to make the change from two horses to three or from three horses to two and have the furrowward horse walk in the furrow unless a stiff tongue were used in one case and a limber tongue in the other case or unless a radical change were made in the disposition of the beam-head casting relative to the disk. The stiff tongue is very objectionable, and the construction of a beam-head casting so it can be changed upon the beam involves serious expense and annoyance. In the present construction a limber. tongue can be used at all times and without change in the beam-head casting.

In Fig. 1 the plow is illustrated as arranged for three horses, the furrowward horse to be hitched to singletree 16 and walk in the furrow, the dissimilar lengths of the ends of the evener 12 causing the strains at the two ends of the evener to be equalized at hitch-point 13 at the forward end of the tongue. The line of strain is in the line of travel and passes through pivot-point 13 and through the disk, such line being parallel with -demonstrative line 20. The tendency of the oblique disk is to run landward or in the direction indicated by line 19. The rear pivot-point 9 of the tongue where it attaches to the beam-head casting is to the landward of the line of draft, the result being a satisfactory running of the plow in spite of the side draft.

\Vhen two'horses are to be used, then the doublet-ree, with its two singletrees, is to be removed from the furrowward end of the ICC) evener and a si'ngletree is to be attached in its place and the evener is to be shifted furrowward upon the tongue, so as to pivot the tongue at hole 14 in the evener. The evener has by this change of its intermediate pivot i become equal-ended and suitable for two horses; but this furrowward shifting of the evener as thus far referred to would only shift it furrowward a distance equal to that between .points 13 and 14:, which is not enough to bring the fnrrowward horse'of the two into the furrow. To bring him into the furrow requires that point 14 shall be moved furrowward to i This brings the evener in proper condition for two horses demonstrative point 21.

with one horse in the furrow; but the tongue will be swungtoo far out of parallelism with the line of draft to bring about the proper. The pivot ati compensation for side draft.

I claim as my invention In a-disk plow, the combination, substantially as set forth, of a beam, a plow-disk obliquely mounted thereon, a land-wheel, arear furrow-wheel, a beam-head having a pivothole substantially in the fore-and-aft line of travel of the disk and having another pivothole to the" landward of the first-mentioned one, a short tongue adapted to have its rear end pivoted at either of said holes in the beamhead, a furrow-Wheel carried by the tongue, stops to limit the swinging of the tongue upon the beam-head, a pivot at the forward end of the tongue, and an evener provided with two holes adapted for alternative pivotal connection with the forward end of the tongue, one of said holes being located at the mid-length of the evener and the other at one-third its length from the furrowward end, said evener being adapted for a singletree at its landward end and for either a singletree or a doubletree at its furrowward end.
